Abstract

See full text

A fixator for internally fixating bone fractures includes an elongate plate portion, a head portion and a barrel extending from the head portion. The elongate plate portion defines at least one plate aperture extending through the plate for receiving bone screws to fasten the fixator to a shaft of a bone. The barrel extends from the head portion and has a generally cylindrical inner surface configured for slidably receiving an end of both keyed and non-keyed lag screws. The cylindrical inner surface further defines at least one keyway along a length of the tube for receiving a key of a keyed lag screw to prevent rotation of the keyed lag screw and for also allowing rotation of a non-keyed lag screw.
